The only team with 75 fans would be Puget Sound which is terrible anyway. There is no drag on tax dollars. The football drag on tax dollars came from building CenturyLink Field for the Paul Allen Seahawks. Most of the kids who play at the "low level" are good athletes.
Bullshit. There are 105 kids on 130 D-1A programs. That's 13,650 kids at elite level. As a comparison there are a total of 5,205 D1 basketball players total out of 347 schools. Now let me blow your "they are good athletes" nonsense out of the water.
There are 124 D-1AA schools with 80 players on each. That's another 9,920 kids. There are 169 D-2 schools. Of course they can only give grants to 36 but they have a ton of walk-on's so lets say they have 55 per team. That's another 9,295 kids. There are 448, yes 448 D-3 schools, which about 250 have a football program. Again, you're looking at an average of around 50 kids per team. That's another 12,500 kids. There are 88 NAIA schools playing football. We can use that same 50 kid metric and be accurate. That's another 4,440 kids.
We might as well add this one; there are 126 JUCO programs out there. I've never seen a JUCO with less than 50 kids on the team, but let's use 50 as the average. That's another 6,300 kids.
Overall we are talking about 51,665 kids playing football after high school. When you factor is basketball, baseball, hockey, crew, golf, and T&F taking their cut out of the athlete pool do you really think the back half of these 50k+ kids are good athletes? Of course they aren't. They are kids that didn't want to stop playing and that's about it. The tax payers and fellow students shouldn't be on the hook for that. If they want to keep playing then join a local semi-pro team and pay for your hobby, because down there that's all it is.
